HIV infection spreads more efficiently during primary infection than during the next stages of infection.

Stage 1

Acute HIV Infection is the first stage of HIV. it develops within two to four weeks after infection of HIV.in the starting of this people face the problems like fever,rashes,cold,headache etc. but people ignore this because of the ignorance it rapidly increase in the body and destroys the T-cells in body. To know whether someone has acute infection, either a fourth-generation nucleic acid test is necessary.

Stage 2

Asymptomatic/Chronic HIV infection is the next stage of HIV infection. During this stage of the disease, HIV continues to multiply in the body but at very low levels. People with chronic HIV infection may not have any HIV-related symptoms, but they can still spread HIV to others. As per increase this infection the T-cells go starts down and the virus level increase in the body.

Stage 3

AIDS (Acquired immunodeficiency syndrome) is last stage of HIV infection. This severally damaged the immune system of the body which result body loss the power to fight with any type of infections in the body because in this stage T-cells came down less than 200 cells in result it increase the illness in body and if any person don’t take treatment of this then AIDS patient can’t live more than three years.
